This application need not to cut off the unloading pipe again through designing neotype unloading pipe when follow-up feed opening water jacket that changes, has also reduced the repair time who changes the feed opening water jacket simultaneously, has avoided because of cutting off the unloading pipe and welds the follow-up frequent hourglass material that causes again.
Description
Technical Field
The utility model relates to a converter equipment technical field, concretely relates to supporting novel unloading pipe that uses of converter feed opening.
Background
The water jacket of the feed opening is positioned at two sides of a flue of a converter opening section and is a connecting part of the flue and the feed pipe, and the feed pipe of the water jacket of the feed opening of the converter is of an integral structure at present. The working condition of the feed opening water jacket is severe, firstly, the temperature close to the furnace opening is as high as 1600 ℃ to cause water jacket burning loss and water leakage, secondly, the smelting raw materials are repeatedly washed to cause water jacket abrasion and water leakage, and once the water leakage trend is enlarged, the feed opening water jacket needs to be replaced. When the feed opening water jacket is replaced, after welding spots of the feed opening water jacket connected with the flue of the furnace opening section are removed and the feed opening water jacket is detached from a flange connecting bolt of a feed pipe, the feed opening water jacket cannot be directly taken out, and the feed opening water jacket is installed to form an included angle of about 35 degrees with the central line of the flue, and the pipeline, the bearing platform and the like around the flue are blocked. If the water jacket is directly taken out, only one section of the blanking pipe is cut off, and the water jacket at the blanking port can be taken out after being lifted up. After the water jacket at the new feed opening is installed in place, the cut part of the feed pipe is installed, and at the moment, because the water jacket is already in place, the space between the water jacket and the upper feed pipe is narrow, and the cut part of the feed pipe is difficult to install. The cut part of the blanking pipe is required to be fully welded with the upper blanking pipe after being installed in place, so that the maintenance time is prolonged, and the welding part is always worn by blanking in the subsequent use process no matter how the welding is carried out, and the phenomenon of material leakage frequently occurs. Even if the cut part of the blanking pipe is connected with the upper blanking pipe by a flange, the cut part of the blanking pipe cannot be installed in place at all because the angle of the new blanking port water jacket after installation is slightly different from the angle of the original water jacket.
SUMMERY OF THE UTILITY MODEL
The utility model provides a converter is unloading pipe mechanism for feed opening, through designing neotype unloading pipe, need not to cut off the unloading pipe again when follow-up feed opening water jacket that changes, also reduced the repair time who changes the unloading opening water jacket simultaneously, avoided because of cutting off the follow-up frequent hourglass material that unloading pipe rewelding caused.
The technical scheme of the utility model as follows:
the utility model provides a converter is unloading pipe mechanism for feed opening, includes converter mouth of a furnace section flue and feed opening water jacket, is provided with unloading pipe, its characterized in that on the feed opening water jacket: the blanking pipe comprises a blanking pipe I connected with a blanking port water sleeve flange, the upper portion of the blanking pipe I is connected with a blanking pipe II, and the blanking pipe I and the blanking pipe II are connected through an annular clamping groove.
Preferably, a pre-tightening spring is arranged in a gap of the clamping groove.
Preferably, the diameter of the blanking pipe I is larger than that of the blanking pipe II.
Preferably, a gap is reserved between the clamping groove of the blanking pipe I and the clamping groove of the blanking pipe II. The angle adjustment is convenient for when this design feed opening water jacket installation.
Preferably, a fireproof blocking layer is arranged between the clamping groove of the discharging pipe I and the gap of the discharging pipe II. The material of the fireproof blocking layer can be high-temperature blocking glue, refractory mortar or fireproof material.
When the water jacket of the feed opening is replaced, the water jacket of the feed opening is detached from the bolt I of the feed pipe, the feed pipe I is lifted, enough space is reserved, and the water jacket of the feed opening can be normally taken out after being lifted. After the new feed opening water jacket is in place, the material pipe I falls down under the action of the pre-tightening spring. The mounting angles of the feed opening water jacket and the feed opening pipe I are slightly adjusted through the clamping groove and the gap and then fixed, the feed opening water jacket and the feed opening pipe I are fastened through the flange bolt, and the feed opening water jacket and the furnace mouth section flue are welded and fixed, so that the mounting of the feed opening water jacket can be completed. After the installation is completed, the gap between the clamping groove of the blanking pipe I and the blanking pipe II is plugged by using a filler, so that the gap between the bottom blanking pipe nipple and the top blanking pipe is ensured, and no smoke can overflow during production.
The beneficial effects of the utility model
The utility model relates to a novelty, simple, easy operation. By using the novel blanking pipe, the blanking pipe does not need to be cut off when the water jacket of the blanking hole is replaced. Meanwhile, the overhaul time for replacing the water jacket of the feed opening is reduced, and subsequent frequent material leakage caused by cutting off the feed pipe and then welding is avoided.
